Technical Field
[0001] The invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device for new material processing. Background Art
[0002] Waste gas is often generated during the material processing and production process, and the waste gas is easily mixed with a large amount of dust. At this time, air purification equipment is needed to absorb and filter the dust in the air to improve the working environment and air quality. Among them, bag dust collectors are the most effective air purification equipment for absorbing dust.
[0003] Existing air purification equipment usually uses a back-blowing method to blow compressed gas out from the inside of a filter bag in a single filter unit, so that the blowing action of the compressed gas causes the filter bag to vibrate to achieve cleaning. However, this method of cleaning the outer wall of the filter bag is prone to stubborn dust residue, and it is impossible to perform targeted cleaning on a certain area of the outer wall of the filter bag.
[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a waste gas treatment device for new material processing is proposed. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides a waste gas treatment device for new material processing, which solves the problems raised in the above-mentioned background technology.
[0006] To achieve the above objectives, the present invention is implemented through the following technical scheme: a waste gas treatment device for new material processing, comprising a gas purification box and a cleaning component, a partition fixing frame is fixed inside the gas purification box, and a filter bag body is arranged in an array on the surface of the partition fixing frame, a back-blowing air pipe is fixed on the upper part of one side of the outer wall of the gas purification box, and the cleaning component is arranged above the partition fixing frame, the cleaning component comprises an air distribution pipe, an air injection head, an inner sleeve of the bag, an electromagnetic valve nozzle, a telescopic spring, a telescopic movable rod, a hollow disk, a supporting upright pole and an annular brush sleeve, the surface of the air distribution pipe is equidistantly provided with air injection heads, and the bottom of the air injection head is fixed with an inner sleeve of the bag, the outer wall of the inner sleeve of the bag is equidistantly provided with an electromagnetic valve nozzle, and the bottom of the inner wall of the inner sleeve of the bag is provided with a telescopic spring, a telescopic movable rod is passed through the interior of the telescopic spring, and a hollow disk is fixed to the bottom end of the telescopic movable rod, a supporting upright pole is fixed at the edge of the upper surface of the hollow disk, and an annular brush sleeve is fixed to the top of the supporting upright pole.
[0007] Furthermore, the gas injection head and the filter bag body are arranged one-to-one, and the interior of the gas injection head is connected with the interior of the sleeve in the bag.
[0008] Furthermore, the inner sleeve of the bag is located inside the filter bag body, and the outer diameter of the inner sleeve of the bag is smaller than the inner diameter of the filter bag body.
[0009] Furthermore, the bottom end of the telescopic movable rod sequentially penetrates the bottom of the inner sleeve of the bag and the bottom of the filter bag body, and the top end structure of the telescopic movable rod is adapted to the internal structure of the inner sleeve of the bag.
[0010] Furthermore, the inner side surface of the annular brush cover is in contact with the outer surface of the filter bag body, and the distance between the annular brush cover and the hollow disk is matched with the length of the filter bag body.
[0011] Furthermore, the dust cleaning component also includes a laser distance measuring sensor, and the laser distance measuring sensor is fixed to the middle of the top surface of the telescopic movable rod.
[0012] Furthermore, the laser ranging sensor and the telescopic movable rod are elastically connected to the inner sleeve of the bag via a telescopic spring, and the vertical center axis of the laser ranging sensor coincides with the vertical center axis of the inner sleeve of the bag.
[0013] Furthermore, an air inlet pipe is fixed to the bottom of one side of the gas purification box away from the back-blowing air pipe, and an exhaust pipe is fixed to the top of the gas purification box.
[0014] Furthermore, the space between the air inlet pipe and the partition fixing frame is an air filter chamber, and the space between the partition fixing frame and the exhaust pipe is a clean air chamber.
[0015] Furthermore, a drying hopper is provided at the bottom of the gas purification box, and a discharge port is provided at the bottom of the drying hopper.
[0016] The present invention provides a waste gas treatment device for new material processing, which has the following beneficial effects: 1. In the waste gas treatment device for new material processing, the gas is pressed into the sleeve inside the bag, so that the gas pressure becomes larger and larger, thereby pushing the telescopic spring downward and contracting, so that the telescopic movable rod descends to carry the hollow plate and the annular brush sleeve downward, thereby brushing off the dust on the outer wall surface of the filter bag body, and the solenoid valve nozzles at various heights are remotely controlled to open. At this time, the compressed air is backwashed from the inside of the filter bag body to the outside to clean the dust. At the same time, after the gas pressure leaks out, the telescopic spring releases potential energy and stretches to reset. At this time, the telescopic movable rod rises, so that the annular brush sleeve slides up along the outer wall of the filter bag body to cooperate with the vibration of the filter bag body to enhance the cleaning effect.
[0017] 2. The exhaust gas treatment device for new material processing, as the electromagnetic valve nozzle opens and closes, the telescopic spring is lifted and lowered by the air pressure. During the lifting process, the laser distance sensor is used to monitor the distance between the top of the telescopic movable rod and the gas injection head in real time, so as to measure the height of the annular brush sleeve in disguised form. Therefore, by controlling the opening and closing time of the electromagnetic valve nozzle at each height, the area where the annular brush sleeve reciprocates can be controlled, so that a certain area of the outer wall of the filter bag body can be precisely cleaned to prevent stubborn dust residue.

DETAILED DESCRIPTION
[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a waste gas treatment device for new material processing, comprising a gas purification box 1 and a cleaning component 5, wherein a partition fixing frame 2 is fixed inside the gas purification box 1, and a filter bag body 3 is arranged in an array on the surface of the partition fixing frame 2, a back-blowing air pipe 4 is fixed on the upper part of one side of the outer wall of the gas purification box 1, and the cleaning component 5 is arranged above the partition fixing frame 2, and the cleaning component 5 comprises a gas distribution pipe 501, a gas injection head 502, a bag inner sleeve 503, a solenoid valve nozzle 504, a telescopic spring 505, a telescopic movable rod 506, a hollow disk 507, a supporting vertical rod 508 and an annular brush sleeve 509, the surface of the gas distribution pipe 501 is equidistantly distributed with gas injection heads 502, and the bottom of the gas injection head 502 is fixed with a bag inner sleeve 503, the outer wall of the bag inner sleeve 503 is equidistantly arranged with solenoid valve nozzles 504, and the bottom of the inner wall of the bag inner sleeve 503 is provided with a telescopic spring 5 05, a telescopic movable rod 506 is penetrated inside the telescopic movable rod 506, and a hollow plate 507 is fixed to the bottom end of the telescopic movable rod 506, a support vertical rod 508 is fixed to the edge of the upper surface of the hollow plate 507, and a circular brush sleeve 509 is fixed to the top of the support vertical rod 508, the gas injection head 502 and the filter bag body 3 are arranged one to one, and the inside of the gas injection head 502 is connected to the inside of the bag inner sleeve 503, and the bag inner sleeve 503 is located on the filter bag body 3, and the outer diameter of the bag inner sleeve 503 is smaller than the inner diameter of the filter bag body 3, the bottom end of the telescopic movable rod 506 passes through the bottom of the bag inner sleeve 503 and the bottom of the filter bag body 3 in sequence, and the top structure of the telescopic movable rod 506 is adapted to the internal structure of the bag inner sleeve 503, the inner side surface of the annular brush cover 509 is in contact with the outer surface of the filter bag body 3, and the distance between the annular brush cover 509 and the hollow plate 507 is adapted to the length of the filter bag body 3; The specific operation is as follows: the gas purification box 1 is a unit structure. When the filter bag body 3 inside any gas purification box 1 is performing a dust cleaning operation, the filter bag body 3 inside other gas purification boxes 1 is still continuing to perform a gas purification operation, and the two complement each other; When the dust accumulated on the outer wall of the filter bag body 3 is cleaned by using the dust cleaning component 5, firstly, the compressed air enters the inner sleeve 503 of each bag along the air distribution pipe 501 and the air injection head 502 through the back-blowing air pipe 4. At this time, the solenoid valve nozzle 504 on the outer wall of the inner sleeve 503 of the bag is remotely controlled to be in a closed state. At this time, as the gas is pressed into the inner sleeve 503 of the bag, the air pressure becomes larger and larger, thereby pushing the telescopic spring 505 to be pressed down and contracted, so that the telescopic movable rod 506 descends to carry the hollow disk 507 to extend downward, thereby carrying the annular brush cover 509 downward through the support vertical rod 508. During the descent of the annular brush cover 509, its inner side surface sticks to the outer wall of the filter bag body 3 and slides down, thereby brushing off the dust on the outer wall surface of the filter bag body 3; After the annular brush sleeve 509 is completely lowered, the solenoid valve nozzles 504 at various heights can be remotely controlled to open. At this time, compressed air is recoil-cleaned from the inside of the filter bag body 3 to the outside. The filter bag body 3 vibrates under the power of the compressed air, thereby shaking off the dust. At the same time, after the air pressure leaks, the telescopic spring 505 releases potential energy and stretches to reset. At this time, the telescopic movable rod 506 rises to make the annular brush sleeve 509 slide up along the outer wall of the filter bag body 3 to cooperate with the vibration of the filter bag body 3 to enhance the cleaning effect.
[0022] like Figure 1-Figure 5 As shown, the dust cleaning component 5 also includes a laser distance sensor 510, and the laser distance sensor 510 is fixed to the middle of the top surface of the telescopic movable rod 506. The laser distance sensor 510 and the telescopic movable rod 506 are elastically connected to the inner sleeve 503 of the bag through the telescopic spring 505, and the vertical center axis of the laser distance sensor 510 coincides with the vertical center axis of the inner sleeve 503 of the bag; The specific operation is as follows: when controlling the opening and closing of the solenoid valve nozzle 504, compressed gas is always injected into the inner sleeve 503 of the bag, and as the solenoid valve nozzle 504 opens and closes, the telescopic spring 505 is lifted and lowered by the air pressure. During the lifting process, the laser ranging sensor 510 is used to monitor the distance between the top of the telescopic movable rod 506 and the gas injection head 502 in real time, thereby measuring the height of the annular brush sleeve 509 in disguised form. Therefore, by controlling the opening and closing time of the solenoid valve nozzle 504 at each height, the area where the annular brush sleeve 509 reciprocates and rises and falls can be controlled, thereby accurately cleaning a certain area of the outer wall of the filter bag body 3 to prevent stubborn dust from remaining.
[0023] like Figure 1-Figure 5 As shown, an air inlet pipe 6 is fixed to the bottom of the gas purification box 1 away from the back-blowing air pipe 4, and an exhaust pipe 7 is fixed to the top of the gas purification box 1, the space between the air inlet pipe 6 and the partition fixing frame 2 is a filter air chamber, and the space between the partition fixing frame 2 and the exhaust pipe 7 is a clean air chamber, and a drying hopper 8 is provided at the bottom of the gas purification box 1, and a discharge port 9 is provided at the bottom of the drying hopper 8; The specific operation is as follows: the air inlet pipe 6 injects the dust-containing air into the filter air chamber inside the gas purification box 1, and the air containing dust rises and passes through the filter bag body 3. At this time, the dust is blocked on the outer wall of the filter bag body 3, and the air rises along the inside of the filter bag body 3 through the partition fixing frame 2 to enter the clean air chamber, and then the dust-filtered air is directly discharged or enters the next process through the exhaust pipe 7, and the dust dropped during the cleaning operation slides down along the inner wall of the drying hopper 8 and is discharged from the discharge port 9, wherein the bottom of the discharge port 9 can be connected to a pneumatic conveying pipeline to transport the discharged dust to the ash storage box.
[0024] In summary, when the waste gas treatment device for new material processing is used, the air intake pipe 6 first injects dust-containing air into the air filter chamber inside the gas purification box 1, and the air containing dust rises through the filter bag body 3. At this time, the dust is blocked on the outer wall of the filter bag body 3, and the air rises along the inside of the filter bag body 3 through the partition fixing frame 2 into the clean air chamber, and then the dust-filtered air is directly discharged through the exhaust pipe 7 or enters the next process; When using the dust cleaning component 5 to clean the dust accumulated on the outer wall of the filter bag body 3, firstly, compressed air enters the inner sleeve 503 of each bag along the air distribution pipe 501 and the air injection head 502 through the back-blowing air pipe 4. At this time, the solenoid valve nozzle 504 on the outer wall of the inner sleeve 503 of the bag is remotely controlled to be in a closed state. At this time, as the gas is pressed into the inner sleeve 503 of the bag, the air pressure becomes greater and greater, thereby pushing the telescopic spring 505 to press down and contract, so that the telescopic movable rod 506 descends to carry the hollow disk 507 to extend downward, thereby carrying the annular brush cover 509 downward through the support pole 508. During the descent of the annular brush cover 509, the inner The side surface is attached to the outer wall of the filter bag body 3 and slides down, thereby brushing off the dust on the outer wall surface of the filter bag body 3; and after the annular brush cover 509 is completely lowered once, the solenoid valve nozzles 504 at various heights can be remotely controlled to open, and at this time, compressed air is backwashed from the inside of the filter bag body 3 to the outside to clean the dust, and the filter bag body 3 vibrates under the power of the compressed air, thereby shaking off the dust, and at the same time, after the air pressure is leaked, the telescopic spring 505 releases potential energy and stretches to reset, and at this time, the telescopic movable rod 506 rises to make the annular brush cover 509 slide up along the outer wall of the filter bag body 3 to cooperate with the vibration of the filter bag body 3 to enhance the cleaning effect; When controlling the opening and closing of the solenoid valve nozzle 504, compressed gas is always injected into the inner sleeve 503 of the bag. As the solenoid valve nozzle 504 opens and closes, the telescopic spring 505 is lifted and lowered by the air pressure. During the lifting process, the laser ranging sensor 510 is used to monitor in real time the distance between the top of the telescopic movable rod 506 and the gas injection head 502, thereby measuring the height of the annular brush sleeve 509 in disguised form. Therefore, by controlling the opening and closing time of the solenoid valve nozzle 504 at each height, the area where the annular brush sleeve 509 reciprocates can be controlled.

Many modifications and variations will be apparent to those of ordinary skill in the art.
